WILLIAM HENRY THOMPSON, OF EAST STROUDSBURG, PENNSYLVANIA.

CASH REGISTER AND DRAWER.

SPECIFICATION forming part of Letters Patent No. 496,585, dated May 2, 1893.

Application filed November 10,1892. Serial No. 51,534. (No model.)

To aZZ whom it may concern.-

Be it known that I,W1LLIAM HENRY THOMP- SON, a citizen of the United States of America, residing at East Stroudsburg, in the county of Monroe and State of Pennsylvania, have invented certain new and useful Improvements in Cash-Indicators, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to cash indicators and particularly to the combination with a manual recorder of a total adding mechanism contained in the desk like form of the box.

My invention includes aseries of key banks, each key of each bank operating a transmit ting device common to all the keys of one bank to a difierent degree; a lock for normally holding the keys against operation by an unauthorized person, said lock being operated at first manually by the cashier to release all the keys and to be operated further by the movement of any one of the indicating keys to look all of the unoperated keys; and means for operating the drawer from the indicat-ing keys when desired or at the will of the attendant preventing such operation, said means therefore including a movable or shifting connection between the keys and the drawer lock which may be controlled by the cashier to throw the keys into or out of engagement with the said drawer look.

In the accompanying drawings: Figure 1 is a vertical sectional view through the casing with the interior parts in side elevation. Fig. 2 is a plan view of one bank of keys of the total adding mechanism detached, and the connection to the drawer lock. Fig. 3 is a transverse sectional view of the adding mechanism on line w0c of Fig. 2, the parts being shown within the case. Fig.4is a plan view of a series of key banks.

The casing 1, may be of any suitable form and is intended to include the mechanism of the manual recorder shown in United States Letters Patent, No. 454,089, dated June 16, 1891, with the exception that the drawer look there shown is omitted. The total adding mechanism includes a shaft 2 upon which three sets of indicating disks 3, 4, 5, for cents, dimes and dollars are loosely journaled, the right hand disk of each set having a pinion 6, combined therewith and having any suitable one way clutch (not shown) between itself and the disk, while between the disks maybe any well known form of carrying mechanism not shown. The pinion of each set is engaged by a rack bar 7, having an extension 8, passing through a guide bearing 9, and under tension of the spring 10, which returns the rack and indicating key to normal position after each operation. Each rack bar has a cross bar 11, at its end through which extend loosely the ends of the key bars of the particular bank of keys to which the rack belongs and is common to all the keys thereof. Each key has free sliding movement through the cross bar which movement is limited by adjustable stop collars 12, on the stems of the keys by which arrangement the different keys of each bank may be made to operate the rack to different degrees by adjusting the collars at greater distances from the cross bars corresponding to the lower denominations of the keys. Thus for the five cent key the collar would be close to the cross bar while for the four, three, two and one cent keys the collar would be arranged at different and increased distances the collar of the cent key being the greatest distance from the cross bar.

Each key bar as shown in Fig. 2 has two shoulders 13, 14. The edges of the bar from the shoulder 14., extends away from the central line of the key thus forming a raised cam edge 15, while on the opposite edge there isa corresponding depression forming a depressed cam edge extending from the shoulder 13, toward the key center, both edges curving gradually from the shoulders. These shoulders are to be engaged by the notched edge of the locking bar lo -the notches in which are the same width as the width of the key bars at the shoulders so that when the notches are made to register with the shouldered part of the bars, the said bars are free to be operated and moved through the notches for operating the indicating disks. The locking bar is arranged to slide transversely of the keys and is pushed normally to the left by a spring 16, so that the edges 17, of the notches will come in front of the shoulders 14, and thus hold all thekeys against movement, until the cashier pushes upon the spring pin 17 and pushes the slide to the right so that all the notches will register accurately with all the shouldered parts of the key bars and then any key may be moved freely through the notch of the locking bar. This action will bring the raised cam edge 15, to work on the edge 17, of the locking bar and a second movement to the right will be given the locking bar by reason of its riding up the raised cam edge and this additional movement will bring the opposite edges 19, of the notches in front of the shoulders 13, of all the unoperated keys and these will be held locked until the operated key has been fully operated and returned to normal position so that the edge 17, will be freed from the cam edge and under the action of the spring forced back into normal position to look all the keys as before mentioned. The push pin for operating the lock manually works through a bearing 20 on the casing and projects under the overhanging edge of the desk being concealed thereby from unauthorized persons.

The drawer 21, is under the tension of a spring 22, to force it out when released. The drawer is held by the pawl 23, on the end of the drawer locking lever 24 under tension of a spring 25. The forward end of the lever is turned up and is provided with a channel or way 26, in which slides a notched bar 27, the notches of which are along the upper edge.

On the under side of the key bars are wedge shaped projections 29, adapted to pass through the notches normally and thus avoid contact with the slide bar and consequently avoid operating the drawer locking lever, so long as the slide bar is held normally to the left under the action of the spring 28.

In order that any key may operate the drawer when moved for operating the registering disk it is necessary to move the sliding bar to the right so that the notches will be thrown out of line with the key wedges 29, and the wedge on any key will then engage the upper intact edge of the sliding bar, thus pushing the same downward and with it the forward end of the drawer locking lever, raising the rear edge thereof to release the drawer. This action of moving the sliding barso that its notches will be thrown out of line with the key wedges is effected by the push pin before mentioned which has an extension 29 to engage the end of the sliding bar when as in Fig. 2, the push pin is first given a quarter turn by the cashier to make the said extension lie in front of the end of the slide bar. Unless the push pin is given this quarter turn there will be no unlocking of the drawer.

when a key is operated and consequently this is a safe-guard against the opening of the drawer by an unauthorized person. The spring about the push pin rotates it back to normal position after each operation.

The mechanism of the autographic register is shown in dotted lines 30 of Fig. 1.

I clai'm 1. In combination the registering disks, the pinion and rack,in connection therewith, the cross bar on the rack and a series of keys having projections to engage the said cross bar,
